IMPROVEMENT IN CLEANING-CARDS OF CARDING-ENGINES.

Specification forming part of Letters Patent No, 11,964, datedNovember 21, 1854.

T 0 all whom it may concern:

Be it known that I, SAMUEL GREENE, of \Voonsocket, in the county of Providence and State of Rhode Island, have invented a new anduseful Improvement in Machines for Carding and Separating Impurities from Cotton; and I hereby declare the following to be a full and clear description thereof, reference being had to the drawings herewith presented, which drawings constitute a part of said description.

This improvementconsists, principally, in a device for taking out the tufts, knobs, and specks, which are found to adulterate more or less all crude cotton. This is performed by a clearing-cylinder which is covered with cardllet, and is made to act constantlyY on the main cylinder of the carding-engine- It is caused to revolve a few degrees at intervals, so as to present a fresh portion of clean card constantly to the main cylinder. By this means it acts as a at or top card, continually catching the tufts and specks and carrying them to the upper side, where a wiper-cylinder wipes them off, and they are then lapped round a wooden roller Y, which lies Aon the top of the wiper, and here the waste is allowed to accumulate from day to day. It may be removed once a week, oroftener, at pleasn ure. If taken off at proper times, it comes in the form of complete bats, thus saving the labor of stripping of top-(plats, and also saving the labor of carding and batting the waste.

In the drawings, Figure 1 is an isometrical view of so much of the machine as will show the application of the several parts. Fig. 2 is a side view of the same.

B is the main cylinder. C is thc clearer-cylinder. This is moved by aratchetwheel R by a catch t' on the lever L. This lever has its fulcrum on the stud of the wheel R, and is actuated by the crank K on the shaft of one of the workers E E and turns thc clearer C by a wheel M and pinion N. It also turns the wiper W by the pinion P. This wiper W' is covered with soft leather. D is the dofting-cylinder.

Fig. 3 is a plan or top view of the same.

Similar letters indicate the same part in each section.

Fi g. 4 shows the gear-wheels (enlarged) which move the clearer and wiper.

It may bc observed thatin this process all the stationary top cards are dispensed with and a more uniform sliver is produced than can be made when top-flats are used and the waste removed periodically. l

As this improvement is applicable to all carding-engines, it will not be necessaryl to give a minute description of the various parts of a machine universally known.

What I claim as my invention, and desire to secure by Letters Patent, is-

The application ofthe clearer-cylinder and wiper, as above described, by which the impurities of the cotton are taken out and formed into a bat.

In testimony whereof I hereto subscribe my name in presence of. two witnesses.

SAMUEL GREENE.
